Distributed Compression of Correlated Classical-Quantum Sources or: The Price of Ignorance
TL;DR: The investigation of the problem of independent local compression of correlated quantum sources, the classical case of which is covered by the celebrated Slepian-Wolf theorem, is resumed, and an achievable rate region is given via protocols that are built on the decoupling principle, and the protocols of quantum state merging and quantum state redistribution.

An information theoretical model for quantum secret sharing schemes

Quantum learning of classical stochastic processes: The completely positive realization problem
TL;DR: This work generalizes some key results of stochastic realization theory, and shows that the problem has deep connections with operator systems theory, giving possible insight to the lifting problem in quotient operator systems.

Bounds on entanglement assisted source-channel coding via the Lovasz theta number and its variants
TL;DR: It is shown that the entanglement assisted independence number is bounded by the Schrijver number: alpha^*(G) <= theta^-(G) and disprove the conjecture that the one-shotEntanglement-assisted zero-error capacity is equal to the integer part of the Lovasz number.
Journal ArticleDOI
Quantum Coding Theorem from Privacy and Distinguishability
TL;DR: In this article, direct quantum coding theorem for random quantum codes is proved for a large class of quantum codes, where only privacy has to be checked. But the problem is separated into two parts: proof of distinguishability of codewords by receiver, and of indistinguishability of codewords by environment (privacy).
